Abstract (en)
[origin: EP0092216A2] 1. A code violation monitor for digital signals in the AMI-code, characterized in that an input (E) is provided for the digital signals, which is connected in series with a Schmitt trigger (ST), a delay element (VL) and a second input (E2) of an error detector (FD), that the error detector includes a changeover switch (T1, T2) which is controlled by a Schmitt trigger output signal which is delayed by one element period relative to the input signal, and further includes two threshold value comparators (T3, T4 ; T5, T6) which are activated by said changeover switch (T1, T2) and of which the first compares the input signal with the lower threshold voltage (UO) and the other compares the input signal with the upper threshold voltage (U1) of the Schmitt trigger (ST), that the input (E) of the code violation monitor is directely connected to a first input (E1) of the error detector (FD), and that in the event of code rule infringements an error pulse can be obtained from that output (A) of the error detector which corresponds to the output of the code violation monitor.
